Adding a context manager for Event

[ThePotatoGuy]

dev QOL addition

Key Changes

• adds a dummy class that does nothing but can be hurt in a variety of ways (MASDummyClass)
• adds a context manager wrapper around Event that can be used to do things to/with an event object without having to None check - MAS_EVL

example:

normal_ev = mas_getEV("a_label")
get_value = None
with MAS_EVL("some_label") as ev:
    ev.unlocked = True
    ev.checkAffection(value)
    cmp_value = normal_ev == ev
    get_value = ev.shown_count
    # etc...

The above will not crash even if a bad label (or no event object found) occurs, unless you write code that would have crashed normally anyway (like calling ev.checkAffection with no arguments, etc...).

In a bad scenario, the behavior of different actions on the ev var vary:

• all Event-based properties return default values
• setting properties does nothing
• function calls do nothing
• the Event class is used as a fallback for everything else.

Two caveats:

1. None checking ev doesnt work (well obviously).
2. when calling a function on a bad ev, the object actually being called on is the MASDummyClass. if pre-determined default behavior is more desirable, then _default_values can be expanded.

Important things to remember

The normal way (None checking mas_getEV) allows us to include backup scenarios if something is off or data is missing. This with version of Event should only be used when we don't care about a bad case.

Testing

• try stuff in console. In general, all things normally done with an Event object can be done with an instance of MAS_EVL regardless of the eventlabel's validity. If the eventlable is real, then the Event object will be modified. Otherwise nothing should happen. And as a reminder, anything that doesn't work with a real Event object will not work with the context manager version.
